Yes, pulseaudio server is running as it is the default in Fedora. I don't like it but there is not much I can do about it. Any plans of supporting non-mmaped access (whatever that means?) ?
I modified limits.conf and I was able to start ALSA driver with regular user, but with Playback only.
I have one Audio card, and the default device should be hw:0,0 in ALSA language, right?
Here are some outputs (all of them with regular user, with realtime privileges enabled in limits.conf)
Jack, full duplex (this one works, despite the warnings):
-----------------------------------------
Connecting to the Jack server...
cannot use real-time scheduling (FIFO at priority -1) [for thread 1792919888, from thread 1792919888] (22: Invalid argument)
Warning: Unable to create "trees" RDF storage.
Performance can be improved by upgrading librdf.
Thank you for using Traverso !

In all of the above I used
Sample Rate: 44100
Buffer latency: 46.44
For the ALSA configurations, I used
Nr. of periods: 3 (although using 2 doesn't change my results)
Dither: None
Thanks for your time.
